Introduction to DVB-GBS 0005r15 By definition, TV-Anytime is independent from By definition, TV-Anytime is independent from The transport layer The transport layer broadcast networks, broadband, mobile networks, … broadcast networks, broadband, mobile networks, … The type of terminals The type of terminals PVR, PC, PDA, Mobile phones PVR, PC, PDA, Mobile phones The group DVB-GBS The group DVB-GBS has specified how has specified how TV-Anytime data must be signaled and carried in DVB transport streams TV-Anytime data must be signaled and carried in DVB transport streams has extended and adapted TV-Anytime has extended and adapted TV-Anytime to fit the unidirectional environment requirements to fit the unidirectional environment requirements to better target low-cost receivers to better target low-cost receivers

Demonstration Synopsis End-to-end TV-Anytime System End-to-end TV-Anytime System Based on DVB-GBS 0005r15 specification for unidirectional delivery of TV-Anytime metadata Based on DVB-GBS 0005r15 specification for unidirectional delivery of TV-Anytime metadata BBC server equipement (Linux server and DVB-T modulator) BBC server equipement (Linux server and DVB-T modulator) Pioneer DVB-T terminal (24MB de SDRAM, 4MB Flash, STM 166 Mhz processor ) Pioneer DVB-T terminal (24MB de SDRAM, 4MB Flash, STM 166 Mhz processor ) EXPWAY BiM software (Encoder & Decoder) EXPWAY BiM software (Encoder & Decoder) Delivery of TV-Anytime EPG via DVB Delivery of TV-Anytime EPG via DVB Metadata service (19 TV & radio channels for 7 days) delivered using the DVB Object Carousel Metadata service (19 TV & radio channels for 7 days) delivered using the DVB Object Carousel Location resolution supported by a separate Content Referencing Information (CRI) service carried in MPEG private sections Location resolution supported by a separate Content Referencing Information (CRI) service carried in MPEG private sections

Modulator DVB multiplex Object Carousel Compiler CRI Service Compiler Metadata Service Compiler TVA Database Stream Player Pioneer STB TV-Anytime metadata files are imported and encoded in order to generate 2 data streams ( metadata and CRI) TV-Anytime metadata files are imported and encoded in order to generate 2 data streams ( metadata and CRI) A DVB multiplex is assembled by combining the 2 data streams together with video streams A DVB multiplex is assembled by combining the 2 data streams together with video streams The complete multiplex is then presented to the modulator through a DVB ASI interface The complete multiplex is then presented to the modulator through a DVB ASI interface System Architecture

TV-Anytime metadata utilized Program Information Table Program Information Table CRID CRID Title (average size: 15 characters) Title (average size: 15 characters) Synopsis (average size: 112 characters) Synopsis (average size: 112 characters) Genre, Keywords, Related Materials (web-site URL), content formats (16/9, stereo,…) Genre, Keywords, Related Materials (web-site URL), content formats (16/9, stereo,…) Program Location Table Program Location Table CRID CRID Program Location Program Location Date/start time Date/start time Duration Duration Demonstration

TV-Anytime vs EIT: a bandwidth advantage… Metadata are 4 times smaller to carry than their EIT equivalent Metadata are 4 times smaller to carry than their EIT equivalent Statistics on the EPG service presented (equivalent to EIT) Statistics on the EPG service presented (equivalent to EIT) Object Carousel Sections - TV-Anytime metadata : 61,2Ko Object Carousel Sections - TV-Anytime metadata : 61,2Ko DVB EIT Schedule Sections : 250,7Ko DVB EIT Schedule Sections : 250,7Ko A format that is therefore suitable from low-end receivers to high-end PVRs A format that is therefore suitable from low-end receivers to high-end PVRs

TVA vs EIT: a Convergence enabler Ex. of TVA EPG based on BBC TVA MD Symbian 6.0, Nokia 3650 platform A format that allows the Convergence with mobile terminals A format that allows the Convergence with mobile terminals Author data once only and enlarge your audience by distributing to many devices Author data once only and enlarge your audience by distributing to many devices

Conclusion A standard suitable to low-end receivers as well as high-end PVRs A standard suitable to low-end receivers as well as high-end PVRs A format reducing bandwidth costs for metadata carriage A format reducing bandwidth costs for metadata carriage A format that allows convergence with mobile terminals & services A format that allows convergence with mobile terminals & services A concrete testing framework in Europe with the UK DTG TV-Anytime Testbed Project A concrete testing framework in Europe with the UK DTG TV-Anytime Testbed Project
